Mark, Tana asked me to send you an e-mail re-summarizing the d/b/a issue.

According to Illinois counsel, there is no quirk in Illinois law that
mitigates against being able to enforce a contract with a party who signs the
contract under a registered d/b/a name. Since we have a copy of the
company's d/b/a filing certified by the Illinois Secretary of State, we
should already have everything we need. In an abundance of caution, we
could ask the counterparty's corporate secretary to certify that "[actual
corporate name]" and "[d/b/a name]" are one and the same entity. But I
personally think even doing that is overkill -- the Illinois Secretary of
State is already basically telling us that in the certificate we already have
in the file.

Feel free to call w/ any comments or questions.
